Claims. (Cl. 222-835) This invention relates to a dispenser for handling portable materials and more particularly to a device adapted for supplying packaged oil to motor vehicles.

The primary object of this invention is to provide a funnel into which a container of oil or the like may be deposited so that the oil in the can may be dispensed into the vehicle without fear of contaminating the oil with dust, or other foreign matter.

The construction of this invention features a dispensing apparatus which is adapted to suitably puncture a can of oil or the like. Means are provided for sealing the interior of the dispenser so as to prevent dust and the like from collecting within the dispenser when the dispenser is not in use. The novel means includes a. resiliently urged flap or plate at the discharge end of the funnel which is opened only when a can is positioned within the dispenser and in a punctured position. A normally closed valve is provided which is only opened upon engagement with the upper surface of a can. Still further objects and features of this invention reside in the provision of a dustproof oil dispenser that is strong and durable, simple in construction and operation, having a minimum number of moving parts incorporated therein so as to be inexpensive to produce, and capable of being easily stored.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this dust proof oil dispenser, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure l is a perspective view of the dustproof oil dispenser comprising the present invention;

Figure 2 is an enlarged vertical sectional view illustrating the device as inserted into the breather tube of an automotive engine and with an oil container inserted in the dispenser;

Figure 3 is an enlarged sectional detail view illustrating the construction of the breather valve incorporated in the apparatus;

Figure 4 is a horizontal sectional view as taken along the plane of line 4-4 in Figure 3;

Figure 5 is a vertical sectional view illustrating the apparatus in position ready to receive an oil container;

Figure 6 is a bottom plan view of the device;

Figure 7 is a horizontal sectional view as taken along the plane of line 7-7 in Figure 5; and

Figure 8 is a sectional detail view as taken along the plane of line -8 in Figure 5 illustrating the construction of the guide and the means for operating the metal closure plate.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 14) generally designates a dustproof oil dispenser comprising the present invention. This device includes a hollow cylindrical body 12 provided with cylindrical side walls and a bottom 14 and which is open at the top. A funnel portion 16 is preferably integrally formed with the cylindrical nite 1. States Patent walls 12 and the bottom 14 and is in communication with the interior of the body 12. The funnel 16 is of a suitable tapering design so as to permit ready insertion into the breather pipe 18 which is connected in the conventional manner to the crankcase of an internal combustion engine.

A cover 20 is provided for the body 12 and is adapted to seal the body against intrusion from dust, dirt, and other foreign matter. The cover 20 has secured thereto an operating lever 22 which is substantially U-shaped in cross-section having a pair of opposed Sides connected by a top portion. Recesses are formed in the sides and are indicated by the reference numeral 24 and open into the bottom edges of the lever 22 for venting a suitable valve 26 adapted to close an opening 28 in the cover 20. The operating lever 22 is suitably hinged as at 30 to the body 12 and a U-shaped member 32 is also pivotally mounted for providing means for readily supporting the dispenser 10 Secured to the cover 20 is a blade 34 of triangular shape which is adapted to puncture a can or container of oil placed within the body 12. The blade 34 is of triangular shape as can be best seen in Figure 4 and underlies the aperture 28 and is of lesser dimensions adjacent the aperture 28 so that the plug 36 forming a part of the valve structure 26 can still engage a portion of the upper surface of the can or container of oil, such as indicated at 38, even after the can has been punctured. The plug 36 is provided with a collar 40 which is of a larger diameter than that of the aperture 23, thereby effectively sealing the aperture against entrance of dust-laden air. When the cover is closed and no can is within the body 12, the collar 40 will therefore seal the device against dust laden air so that the device will remain free of contamination even when not in use for an extended period. The plug 36 is mounted on a rod 42 which is threadedly secured as at 44 into the substantially U-shaped portion of the lever 22 which may be otherwise of any suitable configuration. A coil spring 44 resiliently engages and extends between the collar 40 of the plug 36 and the lever 22.

A handle 46 is secured to the body 12, and attached to the handle for rotary movement is a latch 48 which is adapted to seat within the groove St} in the lever 22 so as to lockingly hold the lever 22 in a closed position.

Secured to the bottom 14 of the body 12 is another cutting blade 52 which is in alignment with the funnel 16 so that the contents of a can, as at 33, punctured by the blade 52, will pour directly through the funnel 16. The can 38 will of course be vented by the opening formed by the blade 34 in the upper portion of the can and by the valve 26 when the plug 36 thereof is urged into an open position so that air may be drawn in through the openings 24 in the sides of the lever 22.

Secured in the interior of the funnel 16 is a guide 54 of substantially ring shape which is held by suitable legs 56 in position. A rod 58 extends through'the central aperture 66 formed in the guide 54 and is rotatably secured as at 62 to a crank arm 64 carried by a closure plate 66 which is hingedly attached as at 68 to the base of the funnel 16 and is adapted to prevent entrance of dustladen air, dirt and other foreign matter into the interior of the funnel while also being adapted to prevent fiow of fluid out of the funnel. The rod 53 carries a platform 70 which is pivotally secured thereto. A coil spring 72 coaxial with the rod 58 resiliently engages and extends between the guide ring 54 and the platform 70 so that the platform 70 is continuously urged into an upper position as is shown best in Figure 5 with the closure plate 66 being urged to a closed position. Only when a can of oil or the like has been placed within the dispenser 10 and the lever 22 has been closed will the platform 70 be depressed, thus opening the closure plate 66 and permitting flow of oil from the can to pass out of the funnel 16. However,

as soon as the can of oil has been removed, no further oil will drip from the funnel 16, thereby making this dispenser convenient and clean to use.

Since from the foregoing the construction and advantages of this dustproof oil dispenser are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications and equivalents may be readily resorted to which fall within the scope of the appended claims.
